Been slowly getting interested in 1998-2001 500SLs (about what I could afford if I sell my 06 Mazda Miata). I have had in past 87 300TD (13 years) and replaced that with 2000 E320 7 years ago (still have). I find many going for some decent prices with low miles in Ca. My Q. What should I look for or stay away from in the years listed? Saw something on the Edmunds site that said 500SLs are gray market cars - is that possible? All the 500SL for sale are gray market?? Also would appreciate any specific sites to look at for some info on these specific models.
